Hi Friends My little 453 has developed an oil leak from the front right hub, I've being looking through the manual and surfing the net for information. The machine has not even hit the 800hour mark so I cant really see the bearings being chewed out but you never know. I was thinking of just replacing the oil seals as I think its just the age of the machine that's the problem and seals do deteriorate over time. Couple of quick questions. Does anyone know of someone in Aust to by the seals from, or even a cross reference number for them OEM 6598829 I can find them over in the states but the shipping costs are crazy. If I need to replace bearings as well, has anyone ever done this on one of these, I watched a youtube of a chap working on a 463 it looked painful! I did read about separating the chain box from the rest of the machine, but there was not information on it. Thanks, and all the best for the up and coming new year to all!
